HORSESHOE-NAlL -FORGING MACHINE.

SPECIFICATION forming part of Letters Patent No. 652,468, dated June 26, 1900.

Application filed October 17, 1899.

To all 1071,0117, it may concern.-

Be it known that 1', CHARLES WELLINGTON VVOODFORD, a citizen of the United States, residing at Port Henry, Essex county, State of New York, have invented certain new and useful Improvements in I-Iorse-Nail-Forging Machines, of which the following is a specification.

My invention relates to horse-nail-forging machines, and will be described with reference to the accompanying drawings, in which I have shown a horse-nail forging machine in which my invention is embodied. I have chosen this particular machine for illustrative purposes only, as the same embodies an efficiently-acting organism for carrying out my invention. The details of my invention will be particularly pointed out in the claims, to which reference is hereby made and wherein the term nail includes nail-blank.

Generally stated, my invention consists in so organizing and combining the elements of a horse-nail-forging machine as to produce a highly-eflicient structure, and in the present instance is shown as embodied in that class of horse-nail-forgin g machines wherein a revolving hammer or planetary roll is employed in combination with laterally-operating die mechanism and means for cutting the nailblank from the stock.

In the accompanying drawings, Figure 1 is a plan view of a nail-forgin g machine in which my invention is embodied. Fig. 2 is a longitudinal sect-ion thereof on the line 2 2 of Fig. 1. Fig. 3 is a transverse section of the machine taken on the line 3 3 of Fig. 1. Fig. 4 is a plan view of the operating-dies, showing the same in their open position. Fig. 5 is a similar plan view showing the dies in what I call their closed position--that is to say, the position assumed by thedies at the instant that the dies cooperate to forge the nail. Fig. 6 is another plan view, similar to Figs& and 5, showing the dies and the cutting mechanism in the positions assumed at about the instant of cutting off the blank from the stock. Fig. 7 is an enlarged sectional elevation of the dies and correlated parts, the section being taken on or about the line 7 7 of Fig. 1. Fig.8 is a detail sectional elevation of the stock-feeding mechanism, which will be fully described,the

section being taken online 8 8 of-Fig. 1. Fig.

Serial No. 7 33,8 7 7. (No model.)

9 is a side elevation, partlyin section, of the means for causing rotation of the feed-rolls for the stock, the section being taken on the line 9 9 of Figs. 8 and 10. Fig. 10 is a sectional elevation of the parts just referred to, the section being taken on the line 10 10 of Fig. 9.

In the drawings, a is the main shaft of the machine. This main shaft 11 carries the planetary roll or revolving hammer I), (see Fig. 2,) which cooperates with the anvil or anvildie 0, carried on the'same die-block c as the side die d. The swinging hammere or reciprocating side die cooperates with the side die d, as will be described. The nosepiece f is carried upon the arm or carrier f, as will be described. A suitable furnace g is located in front of the forging device, and h is a suitable feed mechanism for feeding the stock, all of which parts and the mechanism for moving them will be fully described hereinafter. The main shaft a receives its motion from a suitable pulley or gear a and transmit s this motion by means of suitable gearingfor instance, the spur-gear Ca -to other gearingfor instance, the gear-wheel a carried upon the intermediate shaft '6. The intermediate shaft tis provided with means, such as the pinion F, for transmitting motion to other ge arfor instance, the pinionj on the cam-shaft 7' which cam-shaft by means of the various cams thereon impartsan intermittent movement at'predetermined times to the side die, which, however, is normally stationary when the forging is being ehected. The cam-shaft-j likewise operates the arm or carrier f of the nosepiece, the means for effecting the forward feed of the stock, and

. likewise the means for exerting tension or backward pull upon the stock at a predetermined instant, all of which will be fully described hereinafter. The cutter isbperated by the intermediate shaft 2'.

Iwill first describe the construction and operation of the side die d. This side died, as before explained, is mounted upon the die block or carrier 0, which is pivoted in laterally-adj ustable trunnions c and is preferably provided with an arm 0 provided with a roller 0 which cooperates with an edge-cam on the cam-shaft whereby the cam 7' is operated at predetermined times to impart a double throw to the said die-block by means of the cam portion thereof j j As before stated, the anvil c is rigidly carried upon the swinging die-block c and partakes of its motion. It will be understood, however, that the swinging die-block 0 remains stationary during the forging of the nail, the roller 0 resting upon the plain surface of the rotating cam 7' during such forging, the cam portion j j coming into action when the cutting off of the stock and the feed thereof is being effected. The swinging hammer e is carried upon a swinging carrier or block e, which is pivoted in laterally-adjustable trunnions 6 above the pivot c of the swinging die-block c and between the said pivot c and the point of stroke of the hammer.

By referring to Fig. 7 it will be noted that both the swinging die-block c and the swinging arm 6, as before stated, are carried on trunnions or gudgeons, in contradistinction to the mode of mounting such swinging parts on centers, as heretofore proposed, and are made adjustable longitudinally by means of any suitable adjusting device for instance, the stirrup or strap 6 provided with a screw and jam-nut device 6 e ,'carried thereon and bearing on the trunnions or gudgeons referred to. The constructive relation of these parts is clearly shown in Figs. 4: and 5, which, however, being in plan, show merely the adjusting means for the upper trunnion carrying the hammer. It will be understood, however, that similar devices are employed to adjust the die-block trunnion in the same manner. The hammer-arm 6 receives its motion from a pitman e actuated by an eccentric on the main shaft a. The hammer e is swung each time the shaft a makes a complete rotation, the roll 6 and hammer e acting alternately upon the blank being forged.

Before describing the nosepiece and its operating gear and motions I will describe the means whereby the cutting off of the forged blank is efiected. Carried by the dieblock a is a fixed cutter or cutting edge 0 This cutting edge is stationary when the cutting is being effected and is carried by the lateral swing of the die-block into position to act upon the stock carried in the nosepiece to efiect the severance of the forged blank and cooperates with a movable cutter 70, carried on an arm mounted on a rock-shaft k mounted in a bearing 70 carried by the die-block c. The rock-shaft k is rocked by means of an arm 70, provided with a lug 71: which cooperates with a conical cam-wheel i carried on the intermediate shaft 71. The arm 70 is provided with a suitable spring 7t for retracting the same. The object of making the surface of the cam-wheel 2' conical is to enable the lever 70 to move laterally over the smooth surface thereof when the die-block c is retracted by the spring 0 when the roller 0 rolls' into the depressed portions j j of the cam 3' and at the same time keep the two members of the cutter in their normal position with respect to each other, for unless the arm 10 follows the swing of the die-block the movable cutter must receive some motion. 70 For instance, if the upper face of the camwheel 2' were horizontal the die block 0, swinging laterally and downwardly, would cause the horizontal surface of said camwheel to act upon the rear end of the arm 70 so as to disturb the relative position of the movable cutter with respect to the fixed cutter. As before stated, the nosepiece f is carried by the arm or lever f, which is pivoted at f to alinkf pivotally hung atf from the 0 frame of the machine or other fixed part. The

arm or lever f is provided with a retracting-cwspring f at its rear end, to produce a vertical spring, and with a suitable spring f", herein shown as a leaf-spring, to produce a lateral retraction. This operating lover or carrier f for the nosepiece f receives motion from two cams j j on the cam-shaftf. The cam 7' operates upon the pin f on the lever f to cause a rising-and-falling motion of the outer end of the operating arm orlever f, and thereby producing a raising-and-lowering motion of the nosepiece. This cam j is shown clearly in Fig. 3 and is provided with a series of elevations of substantially the same size and a single elevation f of abnormal size, which elevation f comes into action at the time that the forged blank is to be severed to produce an abnormal lowering motion or vertical drop of the nosepiece to bring the said nosepiece down to the level of the stationary cutter; The back-and-forth motion of the lever f is effected by the cam j, carried upon the camshaft j acting upon a lug f carried upon an arm f on the operating-lever f". This lever, lug, and arm may be integral. As before stated, the lever f, being supported by the pivots f f can be readily swung and moved back and forth, so that the combination of these motions will be made by the nosepiece. The stock is fed through the furnace g to the nosepiece by suitable feeding mechanism, which may be of any desired appropriate character. The feeding mechanism shown in the drawings, and especially in Figs. 2, 8, 9, and 10 thereof, is a good efficient mechanism for this purpose. Referring for the present to these figures and to the plan view Fig. 1, the feed of the stock is effected by a plurality of feed-rolls h 71 which grip the stock between them. The said feed-rolls are suitably supported from the framework of the machine, one of the said rolls being carried upon the shaft h, which shaft carries the disk h. The shaft It carries bosses 72 each provided with an arm h 72, respectively. Pivoted to the arm 72 is a gripper-pawl h which is swung by the link h, pivoted to an arm h (See Figs. 8 and 10.) The forward extremity or shoe of the gripper-pawl 71, is :30 adapted to bear against the periphery of the disk h when the pawl h is swung on its pivot, so as to grip the edge of the said disk to produce a forward rotation of the disk IIO when the pawl is lifted. The lever h is pivoted at 7t and is provided at its opposite end with a spring 71 This lever is operated by the cam which is shown as provided with a plurality of elevations 7' j to cause the feed-works to make a double forward movement. The pawl 72, is provided with. a suitable adjustable restoring-spring hi The operation of the parts just described will be readily understood. It may be stated, however, that when the cam 7' causes the lever h to be swung upward the shoe 7L6 of pawl 7L8 grips the periphery of the disk h, and as the lever It continues to move upward it will carry with it the pawl, which swings on the shaft 7113 as a center, and will thereby move the rotating disk 72, and the feedrolls one step forward. The cam 3' is shown as cut to produce two forward steps for every nailfeed. I have likewise provided means for producing a slight backward pull on the stock when the same has been gripped by the side dies. In order to do this, I impart to the feedrolls a slight backward movement as follows: The swinging arm 77. has pivoted thereto a pawl h similar to the pawl h and provided with a similar restoring-spring 71 This pawl h is pivoted to a link 77, which in turn is pivoted to the lever h". The lever h" is pivoted to bracket h, is provided with a restoringspring h, and is acted upon by the cam If". This cam h is provided with elevations orcam portions h 7W 71 The operation is as follows: Just before the finished nail is moved into position to be severed from the stock and while it is still gripped by the dies the cam 71 comes in contact with the lug h on the lever h", and thereby raises the said lever, drawing upon the pawl 71 and swinging the disk h backward, thereby producing abackward pull upon the stock, which has the effect of straightening out any bends orirregularities in the stock, and during the time that the lug h is riding upon the elevation h the nail is being severed by the cutters. The succeeding elevation 71 is to cause a slight backward pull upon the rod during the interval between the two steps of the forward feed thereof produced by the elevations j j on the cam j". The amount of throw imparted to the feed-rolls by the pawls may be efficiently regulated by regulating the throw of the said pawls, which, as the pawls are pivoted upon the swinging arms and the swinging links, may be effected by the adjustingscrews h which, lying beneath the middle pivotal points of the pawls, may be adjusted upward or downward to limit the stroke of the said pawls or to even entirely disengage the said .pawls from the disk 7Z4.

Having described the construction and location of the parts of the illustrative machine shown in the drawings and their relation to each other, I will now proceed to describe the detailed operation of the machine.

Let it be supposed that the stock has been fed onto the anvil. As is well known, the rothe arm f. The stock is laid upon the anvil to be operated upon by the planetary roll and is then raised and moved laterally against or in front of the side die, to be operated upon by the swinging hammer, this diagonal motion being the resultant or component of the two motions imparted to the lever or nosepiece carrier f by the cams 3' 7' carried on the cam-shaft 7' WVhen the planetary roll I) and hammer e have made the requisite number of motions, (I have shown provision for ten in the drawings, although the number may be reduced to seven or any other eflicient number which may be desired,) and while the nail-blank is still gripped between the hammer and side die, the cam h comes into action to produce the backward pull upon the stock in the manner heretofore described in order to straighten out any bends or kinks or defects which may have occurred in the said stock, holding the stock in the retracted position as the lug 71 of the lever h rides upon the cam 72, until the nail has been severed by the cutters, which operate at this time as follows: When the planetary roll and hammer e have completed their motions as aforesaid, the roller 0 falls into the cut-away portion j of the cam j thereby swinging the die-block c and side die and anvil laterally to the right, removing the anvil from beneath the nail, so as to leave the nail-blank still attached to the stock and supported by the nosepiece. Then the projection f on the cam f operates upon the lever f, thereby swinging the nosepiece f vertically downward, level with the bottom cutter 0 carried by the die-block. Then the roller 0 as the camshaft j continues to revolve, drops into the deeper recess or cut-away portion j of cam j thereby further swinging the dieblock 0 and bringing the cutters 0 7c in position to operate to cut oif the nail from the stock, it being remembered that the lever swings over the conical surface of the cutteroperating cam i and is swung upward to effeet the cutting by the cam-piece carried by the said operating-cam. After the nail is severed the cams operate to restore the dieblock to initial position and to likewise restore the nosepiece to its initial position, and during this period of restoration the first forward feed of the stock is effected by the feedrolls, which are operated, as described, by the pawls acted upon by the lever 7L which is moved by the first cam projection j of the cam j After this forward movement of the stock it receives another slight backward pull, caused by the lug 72 riding up on the cam 71 (see Fig. 10,) the lug of the lever h at this time resting in the depression between the cams j j The lug It now drops into the recess which follows the cam h, and the lever 71 is acted upon by the second cam 9' to effect a further forward movement or step of the stock, and thereupon the lug h rides up the incline k and resting upon the concentric surface of the cam h holds the feed-wheels stationary to prevent any forward motion of the stock while the nail is being forged.
